Well, your BP was only borderline high before treatment, and a blood pressure of 130-140/90 will not cause heart failure.

IRBBB (or RBBB) is very common (I think 10-15% of us have that) and not a sign of heart failure. If you are able to jog for 45 minutes daily without any problems like shortness of breath or chest pain, you do NOT have heart failure. Left bundle branch block (LBBB) on the other hand, is linked to heart disease.

Have you registered an EKG earlier? Did that also show IRBBB? In that case, you are likely born with it. Often, a well-conditioned heart (athletes heart) also develops IRBBB for some reason.

The only slightly confusing part of your description is your QRS axis of -102 degrees. Are you sure it's not 102 (as in +102)? Anyway, your doctor wrote normal electrical axis so it probably doesn't matter.

"rabbit ear" QRS complex (initial positve, negative, and positive at the end) is seen in the V1 lead. A normal QRS in V1 has a little upstroke which reflects right ventricle depolarization, then a fairly deep downstroke (negative force from left ventricle which has far larger muscle mass). The initial upstroke is supposed to be higher and higher down the V1-V5 leads as the electrodes are closer to the left ventricle. An inverted T wave in III is as far as I know fairly nonspecific and may both occur with and without (I)RBBB.

With IRBBB you will usually also see a deep S wave (downstroke) in V6, which is usually not there, which represent the un-upposed late right ventricular depolarization (forces are not evened out by left ventricular depolarization).

Sorry - I don't know the answer to your last question. Anyway, IRBBB is a common and normal variant, if your internal med doctor approved your EKG as normal, you should trust that :-)

Unfortunately, I can't answer your question. We don't have health insurance in my country, (we have some types of insurances which can guarantee certain treatments within a time limit, but they don't work the same way as US health insurance), so I don't know. I wouldn't think so, as IRBBB is common and normal.
